Tapping our passion for performance motorbike accessories as well as experience and know-how, we set up Yah Shr Da Enterprise Co., Ltd. and the same house brand in August 2003. We first developed a fuel filter and LED directional signal for universal applications and successfully won customers’ favor. Later, we developed motorcycle/scooter CVT weight bearings and brake switches. Apart from the four aforementioned products, we focus on developing advanced electronic motorcycle/scooter lights and performance-tuning accessories.
